I don't need to understand field archery, Arthur. I don't DO IT. I'm not the one telling you that your way's all in your head!....lol

And wait a danged minute.....you've never even TRIED to do what we're talking about??? You know....I'm not sure you fully understand what we're even talking about (yes...I've done it 'your way'). I DO NOT "center a round pin guard" in my peep. I'm telling you.....and imagine this.....when I come to full draw...and look through my peep....it aligns PERFECTLY with my pin guard (making the pin guard 'disappear'). If I SEE the pin guard....I know I'm not PERFECTLY aligned. When I see NO PIN GUARD......I put the pin on my intended target......and I hit what my pin's on.

I really am not sure you grasp this.

And again....I don't give a rat's ass how YOU do it. Just don't tell me my way is my mind playing smoke and mirror tricks on me (especially if you've never even tried it!).
